Noise Inside the Unit!
You may notice that your unit makes some unusual noises. Most of these are perfectly normal, but you should be
aware of them!
These noises are caused by the circulation of the refrigerant liquid in the cooling system. It has become more
pronounced since the introduction of CFC free gases. This is not a fault and will not affect the performance of your
unit. This is the compressor motor working, as it pumps the refrigerant around the system.

ALARM
High
temperature alarm and
Low
temperature alarm
a
、
If the displayed temperature > SET tempe high temperature alarm SET value H, then the buzzer will alarm
and the digital tube will flash the high temperature alarm code "H1" alternately at the interval of 3 seconds each
time.
b
、
If the displayed temperature <SET temperature - Low temperature alarm SET value L, then the buzzer will alarm
and the digital tube will flash the low temperature alarm code "L1" alternately at the interval of 3 seconds each
time.
If the temperature of ambient sensor > High Ambient temperature alarm value tH1 (sensor is normal and not
shielded, then the buzzer will alarm and the digital tube will flash the high ambient alarm code "H2" alternately at
the interval of 3 seconds each time.
Door open alarm
After the door is opening for t4 minute(s), then the buzzer will alarm and the digital tube will flash the door open
alarm code "do". Alarm will be canceled after door closed.
Power failure alarm
When the supply voltage is below 9.5V, the buzzer will alarm and the digital tube will flash the power failure alarm
code "PF". When the detection voltage is higher than 20V, The buzzer will alarm and the digital tube will flash the
power failure alarm code "EP" meaning Power Supplies is not working.
Low battery alarm
When the low battery function is available, if the voltage of back up battery is lower than 10.8V, the buzzer will
alarm and the digital tube will flash the low battery alarm code "BL", Alarm will be canceled when the voltage of
back up battery is higher than 12V. When the detection voltage is higher than 20V. The buzzer will alarm and the
digital tube will flash the power failure alarm code "EP" meaning detection voltage circuit is not working.
When the low battery sensor is not shielded , When the measured temperature is less than or equal to -50
℃
or
greater than or equal to 100
℃
, the sensor will be judged to be faulty. The alarm codes of TP1 to TP6 are E1 to E6
respectively. When the humidity sensor is not shielded, the alarm code is E7. The buzzer will alarm and the digital
tube will flash with relative code.
